Description

FIELD OF THE INVENTION

The invention relates to a motor vehicle flashing light with a plurality of light emitting diodes (LED) arranged in a row. The invention also includes a method for operating a flashing light, in which a plurality of LED groups each comprising at least one light-emitting diode are arranged in a row. Direction indicators of the type mentioned are, for example, from the DE 10 2011 119 230 B4 known. Furthermore, the present invention also includes the use of such a flashing light for signaling a change in the motor vehicle locking device, or for optically signaling a state of the vehicle locking system, and a motor vehicle equipped therewith.

Direction indicators, or blinkers for short, are provided in motor vehicles as direction indicators. They are switched on and off alternately within a blinking cycle (activated and deactivated again), i. H. each flashing cycle consists of an active period during which the flashing light is on and an inactive period during which the flashing light remains off. The flashing frequency is between one and two Hertz. Certain legal framework conditions must be met for turn signal lights approved in road traffic. In a motor vehicle, for example, all indicators that indicate a particular change in direction of travel must be illuminated in the same phase, i.e. H. the active periods of the different turn signals must overlap.

As a generic font of such flashing lights is the font DE 10 2011 119 230 B4 to name, which to avoid repetition, is to be fully assessed as state of the art, or which is completely part of the disclosure content of the present invention.

TECHNICAL BACKGROUND

In modern vehicles, as a rule, the turn signals are now used, in addition to the actual function of the direction indicator, to visually signal the opening and closing process of an opening and closing process of the motor vehicle locking system, whereby turn signals with a running light effect according to the previous one are also used described prior art are used.

A distinction between the optical signaling with regard to the locking process or the vehicle locking and the unlocking process or the vehicle unlocking is currently only possible on the basis of a different number of flashing cycles, with the user (viewer) losing unambiguity or differentiation in a fleeting inspection Whether a locking process or an unlocking process of the vehicle locking system after the activation of the identification transmitter / access authorization transmitter / radio remote key or sensor device on the motor vehicle was effected by the authorized user is only possible by careful observation. The latter means that, in the event of accidental incorrect operation by the identification transmitter / access authorization transmitter / radio remote key or the sensor device on the motor vehicle by the authorized user, an unintentional state of the vehicle locking system can erroneously occur without the vehicle user having to do this, for example Leaving the vehicle is perceived, and thus ultimately the vehicle remains unlocked without supervision.

In the flashing light ( 10 ) there is a printed circuit board ( 12 ) (Printed Circuit Board - PCB) on which, for example, a total of light-emitting diodes ( 16 ) are soldered on. For the sake of clarity, the LEDs ( 16 ) in 1 only provide a light emitting diode with a reference symbol.

On the circuit board ( 14 ) are the light emitting diodes ( 16 ) arranged here in a straight row. The circuit board ( 14 ) is in the flashing light ( 10 ) behind an orange colored, transparent pane. The light of the light emitting diodes ( 16 ) is therefore recognizable to an observer as orange light from the outside. Instead of a single circuit board ( 14 ) can also be provided to arrange the light-emitting diodes distributed over several circuit boards.

As from the 1 can be seen further, the circuit board ( 14 ) via lines ( 18 ) with a control unit ( 20 ) connected. Via a control input ( 22 ) receives the control unit ( 20 ) a voltage signal, which is a control signal ( U ) for the flashing light ( 10 ) represents. The control signal ( U ) is generated by a control unit (not shown) of the motor vehicle. At the control unit ( 20 ) can be, for example, a microcontroller or a signal processor.

The LEDs ( 16 ) are on the rising edges of the individual controls of the control signal ( U ) from the control unit ( 20 ) over the lines ( 18 ) not switched on at the same time. Instead, depending on the order ( R1 . R2 ), or the direction ( R1 . R2 ) the first group ( 24 . 24 ' ) switched on as the starting group and then one after the other R after, the other groups ( 26 . 28 . 30 , respectively. 26 ' . 28 . 30 ' ) and finally the last group ( 32 . 32 ' ).

With a falling edge of the control signal ( U ) then all groups ( 24 to 32 , respectively. 24 ' to 32 ' ), ie all light emitting diodes ( 16 ), switched off again. This flashing cycle may then be repeated with the next rising edge of the control signal ( U ).
